Fluorescent lamp lumens table.
3 minute read the ultimate guide by viribright charts tables and more over the years advances in technology have brought about innovations in how to light our homes and commercial buildings.
The increased use of fluorescent and led bulbs we use less watts to produce the same amount of lumens saving us money on energy bills.
And how do you understand what are lumens in light bulbs and light fixtures.
In addition to being the internet s premier modern lighting and design store hey that s us lumens is now the way to find out how bright a lighted bulb or integrated led lighting.
We want the correct amount of light for each setting in our homes.
To replace it with the same intensity led just look for one that rates around 2300 lumens.
Lumens to watts calculator watts to lumens calculation.
How to choose the right kelvin color temperature.
The bulbs we ve taken into consideration here are the old incandescent ones led s as well as fluorescent bulbs cfl.
Fluorescent tube lighting comes in a range of sizes.
Light bulb color temperature is represented in the unit of absolute temperature kelvin noted by the symbol k.
A 40 watt fluorescent tube for example is rated around 2300 lumens.
In the table below you can see how lumens roughly translate into watts according to different types of light bulbs.
Energy saving lamps have high luminous efficacy more lumens per watt.
The power p in watts w is equal to the luminous flux φ v in lumens lm divided by the luminous efficacy η in lumens per watt lm w.
But what are lumens exactly.
Therefore we need to know the right amount of lumens and find the light bulb that will generate that light.
In the commercial sector fluorescent lamps are often used to illuminate offices workshops or halls.
Household fixtures are commonly found in color temperatures on the kelvin scale of 2700k warm incandescent 3000k warm white halogen and 3500k household fluorescent.
Now we have compact fluorescent lamps cfl a.
In the beginning all we had was the standard incandescent light bulb.
The luminous flux φ v in lumens lm is equal to the power p in watts w times the luminous efficacy η in lumens per watt lm w.
These are used in private households for example to illuminate basements or garages.
What is a lumen.
Of course not every fluorescent incandescent metal halide etc lamp will give its lumens.

Fluorescent tubes are available in a wide variety of types and sizes.
T5 and t8 fluorescent tubes are the most commonly used types today.
Determining the tube size of the fluorescent light will help you decide which tube lighting is a suitable replacement.
When you are trying to replace fluorescent lighting whether with leds or another tube you will need to understand the difference between tube light sizes.
The more lumens a light bulb produces the brighter it shines.
Lighting it s all about lumens.
